Abstract

L’invention concerne un dispositif de protection (10) d’un instrument optique (11) d’un satellite (100), l’instrument optique (11) étant destiné à pointer selon un axe de pointage (12), ledit dispositif de protection (10) étant caractérisé en ce qu’il comprend : un support (13), l’instrument optique (11) étant disposé sur le support (13) et orienté selon un premier axe (14), un écran solaire (15) comprenant des parois (16) et une ouverture (17), les parois (16) formant une cavité (18) ; en ce que l’instrument optique (11) est disposé dans la cavité (18) de l’écran solaire (15), et en ce que le support (13) est mobile en rotation autour d’un deuxième axe (24) distinct du premier axe (14), de sorte à faire passer l’instrument optique (11) d’une position de pointage dans laquelle le premier axe (14) est sensiblement confondu avec l’axe de pointage (12) à une position de protection dans laquelle le premier axe (14) et l’axe de pointage (12) sont distincts, et/ou de la position de protection à la position de pointage. Figure pour l’abrégé : Fig. 1The invention relates to a device (10) for protecting an optical instrument (11) of a satellite (100), the optical instrument (11) being intended to point along a pointing axis (12), said device for protection (10) being characterized in that it comprises: a support (13), the optical instrument (11) being arranged on the support (13) and oriented along a first axis (14), a sunscreen (15) comprising walls (16) and an opening (17), the walls (16) forming a cavity (18); in that the optical instrument (11) is arranged in the cavity (18) of the sunscreen (15), and in that the support (13) is rotatable about a second distinct axis (24) of the first axis (14), so as to move the optical instrument (11) from a pointing position in which the first axis (14) is substantially coincident with the pointing axis (12) to a protection position in which the first axis (14) and the pointing axis (12) are distinct, and/or from the protection position to the pointing position.
